I don't think so,is anything showing amiss in device manager,it may be a driver problem.Should the webcam be listed in BIOS?
Ah,sorry I didn't notice that,and I know very little about Linux systems.Installed OS is xubuntu 13.04 by the way.
And did you remove the wee transparant, protective sticker that might prevent the camera from working? That made mine 'faulty' until I noticed that bit. Btw A quick easy way to check the camera, is to use it with videolan (VLC -> media -> open capture device -> Capture mode =video for linux 2 ; video-device = /dev/video0 on my slakare box)...I Does lshw or lsusb or lspci show the existence of a webcam, and is it possible that yours is faulty?
